4 Inch Stainless Steel Exhaust V Band Clamp Male Female Flange Assembly,4 Inch V Band Clamp with Flanges for Turbo Downpipes Exhaust Systems (4 inch)

It was easy to weld and no leaks

I like the simplicity of the product. A little time to set up everything, yet saved a lot of work in the future.

Not stainless steel, no lip for alignment... even a test fit of the clamp shows that the unit wont properly align like a standard vband. Knew the price was too good to be true.

This holds your pipes to never lose strength in separation to keep everything attached together.

Great quality vband at reasonable price

works great thanks

Works great would by again

This piece of crap will never seal. When I bought it, the picture that came up was the style where the flanges have a lip that overlap. This useless piece of crap is heavily chamfered on both sides. The clamp does not center the two pieces as you tighten it, and worse yet the threads are about half as deep as they should be on the bolt side, so the nut started to jamb up about half way down. I am so stupefied by this thing that I went back to the ad and looked. Sure enough, the first picture that comes up for the 2" clamp is the style with the overlapping flanges. However every picture after that is this dumb thing. I did not realize I had to get a magnifying glass out and examine each picture in the ad closely, so as to not get ripped off.I read the other poor reviews, and sure enough a couple people are speaking of this. The only thing I can think is this was originally designed to have some kind of a gasket in it...The best part is, I've used enough cheap v-bands purchased on Amazon (without problems), that I didn't even pay that much attention, and now one side is already welded on GRRRRRRR!!!
